Fig. 3From: Anterior cruciate ligament reconstruction with quadriceps tendon-patellar bone allograft: matched case control studySide to side ratio of peak torque values by Cybex isokinetic testing at 60° (left) and 180° (right) per second. Vertical full line indicates the standard deviation of the peak extension torque in QTPB allograft group. Vertical dotted line indicates the standard deviation of the peak extension torque in QTPB autograft group. QTPB = quadriceps tendon patellar boneBack to article page
